The results show that the dissolution process of prefabricating alloy can be divided into two periods when the temperature of zinc melt is below the melting point of aluminum.Firstly,zinc melts infiltrates into the prefabricating alloy and then Zn-Al-TiC alloy forms in the surface layer of the prefabricating alloy.Secondly,the Zn-Al-TiC alloy of this alloy surface layer begins to dissolve to the zinc melt.

结果表明：当锌熔体温度低于铝熔点时，预制合金的溶解可分为两个阶段：第一阶段为液态锌向预制合金中浸渗，并在预制合金表层内形成Zn-Al-TiC合金；第二阶段为预制合金表层内的Zn-Al-TiC合金开始溶解并进入锌熔体。
